rather than the other way around, since tooling doesn't seem to support building version strings from version tuples these days.

use lighter subset of pep440 since we don't need every kind of version it can handle

alternative: use packaging.version.Version for parsing, build tuple from there, e.g.

_v = Version(__version__)
version_info = _v.release # (x, y, z)
if v.pre or v.dev or v.post:
    version_info = version_info + (__version__[len(_v.base_version):].lstrip("."),)
